  • the adjustment of the distance between two such display elements is important, on the one hand for mechanical reasons to avoid any interference, and on the other hand for optical reasons, to offer the user a sharpness of vision of the markings located on all floors of the timepiece.
  • optical conductor in particular a bundle of optical fibers, or other display element
  • optical conductors in particular bundles of optical fibers
  • this is essential to reproduce a pattern that is not blurred.
  • it is necessary to avoid variations in height between the patterns which would be perceptible to the user.
  • the invention proposes to improve a timepiece display device, comprising several display elements, on several parallel or substantially parallel levels, so as to avoid interference or friction between some of these elements, by introducing means for controlling the distance between two display elements, and, more particularly, means for adjusting the distance between two display elements.
  • the invention relates to a timepiece display device according to claim 1.
  • the invention also relates to a timepiece, in particular a watch, comprising at least one such display device.
  • the invention relates more particularly to a timepiece display device 100, which comprises a first display element 1 and at least one second display element 2 that are substantially planar, which are superimposed above a fixed part 50 comprising a main bearing surface 51.
  • this device 100 extends over several parallel or substantially parallel levels, and comprises, separated from the user by a glass 10, the first display element 1 which is substantially plane, that is to say plane or curvature greater than 10 cm, comprising a first upper surface 11 visible to the user and opposite the first lower surface 12, and, separated from the crystal 10 by the first display element 1, at least one second display element 2 substantially flat, that is to say flat or with a curvature greater than 10 cm, comprising a second upper surface 21 visible by the user and a second lower surface 22 opposite the second upper surface 21.
  • Each second element of display 2 is movable above the main support surface 51.
  • the lower return means 52 tend to move at least one second display element 2 away from the main surface 51 to bring this at least one second display element closer.
  • the upper return means 63 and/or the spacing means 60 are arranged to ensure a functional clearance Em between this at least one said second display element 2 and the first lower surface 12. More particularly, at least two second display means 2 are staged at different distances from the main surface 51, and are kept separated from each other by spacer means 60 included in the device 100.
  • the first display element 1 comprises on the one hand at least a first screen surface 18, which is visible to the user, and which is arranged to locally hide from the sight of the user at least a part of the second upper surface 21 of a second display element 2 located between the first display element 1 and the main support surface 51, in a front direction of vision F, substantially normal to a plane tangent to the first upper surface 11 of the first display element 1 or to a second upper surface 21 or to the main bearing surface 51.
  • This first display element 1 also comprises at least one first viewing zone 19 which is a opening or an optical conductor or a transparent or translucent zone, which at least a first vision zone 19 is arranged to allow the user to see at least part of a said second upper surface 21, and/or a saying of second lower surface 22 when the second display element is transparent, of a second display element 2 located between the first display element 1 and the main support surface 51, in the front direction F.
  • first viewing zone 19 is a opening or an optical conductor or a transparent or translucent zone, which at least a first vision zone 19 is arranged to allow the user to see at least part of a said second upper surface 21, and/or a saying of second lower surface 22 when the second display element is transparent, of a second display element 2 located between the first display element 1 and the main support surface 51, in the front direction F.
  • the device 100 comprises spacing means 60, the bearing surface 600 of which is arranged to cooperate with the abutment surface 210 that comprises a second upper surface 21 of a second display element 2, and this abutment surface 210 is masked by a first screen surface 18, and is not visible to the user.
  • This description sets out different variants of the invention in particular and non-limiting applications, relating to the positioning in a front direction F of a mobile display element 2 relative to a sapphire dial 1, to an optical fiber 70, or to another movable display element.
  • the figure 1 represents such a display device 100, comprising a first display element 1 on the user's side, here represented by a sapphire dial, and a second display element 2, which here is a display disk movable around an axis of rotation D, which are both substantially flat, and which are superimposed above a main surface d support 51 that includes a fixed element 50 such as a plate or the like.
  • the arrow F indicates a front direction of vision, substantially perpendicular to the first display element 1, or to the second display element 2, or to the fixed element 50.
  • the first display element 1 comprises here, on its face lower, that is to say opposite the user, a covering, of which a first upper surface 18 is visible to the user, and of which a first lower surface 12 faces the second display element 2 located below.
  • This second display element 2 comprises, on its upper face 21, which is visible to the user when it is not hidden by the coating of the first display element 1, at least one display pattern which can be viewed by the user in an opening 19 or a window 80 that comprises the first display element 1.
  • This second display element 2 is remote from the main support surface 51 by lower return means 52, shown here by elastic return means such as a spring, which tend to push it towards the first display element 1, from which it nevertheless remains distant thanks to spacing means 60, which ensure a minimum functional play between this first element of display 1 and this second display element 2.
  • these spacing means 60 comprise damping means, which are arranged to provide a shockproof abutment function to prevent any contact between said second display element 2 and said first lower surface 12 during an impact. undergone by the timepiece carrying said display device 100; in particular these spacing means 60 advantageously comprise at least one elastic element, to absorb the effects of a shock if necessary, for example during a fall of the timepiece, and to safeguard the integrity of these two display means 1 and 2.
  • these means spacers 60 are in an area invisible to the user, for example in the vicinity of the axis of rotation of the mobile display to reduce the tangential friction during a change of display; they can either be carried by the first display element 1, by the second display element 2, or even by a fixed element 50 linked to the plate for example.
  • spacing means 60 are arranged to ensure a non-zero functional clearance Em, visible on the figure 1 , between this second display element 2 and the first lower surface 12.
  • their bearing surface 600 is that of a Teflon ® component or which is Teflon coated or similar, to reduce the tangential friction during a display change.
  • the dial may in particular comprise a sapphire plate 120, with a paint or coating 180 under the sapphire in order to color the dial. More particularly, an opening or a transparent or translucent zone 19, or even a window 80, for a display, leaves a transparent part or even a through hole in the dial 1.
  • the second display element 2 which is below seems to be at the same level as dial 1, because it is only slightly spaced from the visible dial (distance E on the figure 1 ). It is therefore necessary to minimize this distance E and to control it.
  • the means lower return element 52 comprise at least one elastic return element 52, which presses the second mobile display element 2 against the abutment surfaces 600 that these spacing means 60 comprise.
  • At least one second display element 2 is a second upper display element which comprises, on the one hand at least one second screen surface 218 visible to the user and which is arranged to, or else hide in view of the user any second upper surface 21 of another second display element 2 which is a second lower display element, or to show the user two superimposed patterns.
  • This second lower display element is located between, on the one hand the second upper display element 2 and the main support surface 51, in the frontal direction of vision F substantially normal to a plane tangent to the first upper surface 11 of the first display element 1 or to a second upper surface 21 or to the main bearing surface 51, and on the other hand at least one second viewing zone 219 which is an aperture or an optical conductor or a transparent zone or translucent, which at least a second viewing zone 219 is arranged to allow the user to see at least a second upper surface 21, and/or a second lower surface 22 when the second display element 2 is transparent, of a second lower display element located between the second upper display element and the main support surface 51, in the front direction F, as visible on the figure 7 .
  • the figures 7 and 8 show two second display elements 2, which are two display discs: with the aim of producing a pattern composed of two digits substantially at the same height (spaced by the smallest possible distance E), several elements of movable display between them can be positioned by stops and elastic or magnetic return elements. The two patterns therefore seem at the same height if it is low.
  • the achievements of figures 7 and 8 make it possible to produce a large date, for example, with the second upper display element 2 which is a tens disc which bears tens markings 218, and the second lower display element 2 which is a units disc which bears unit markings 219.
  • optical conductor is meant here an image transfer device, to bring back an image present on a lower level towards the user, possibly with a magnification effect, or other. More particularly, such an optical conductor comprises at least one bundle of plastic or polymer or glass optical fibers, or the like. Another case of distance adjustment thus concerns optical fibres, as illustrated in the figures 2 to 6 .
  • the use of an optical conductor or bundle of optical fibers aims to move a display pattern in a frontal direction F over a large distance (via the optical conductor or the bundle of optical fibers). This allows other means of distance adjustment. As a reminder, the adjustment of the distance between the pattern to be reproduced and the optical conductor or the bundle of optical fibers is essential to avoid obtaining a blurred pattern.
  • At least the first display element 1 comprises at least one optical conductor or a bundle of optical fibers 70, an upper surface 71 of which is visible to the user to whom it transmits the image of a second upper surface 21 of a second display element 2, in the vicinity of a lower surface 72 that comprises the optical conductor or bundle of optical fibers 70, and the lower surface 72 closest to the main surface 51 then constitutes the first lower surface 12 of the first display element 1.
  • the device 100 comprises spacing means 60, which comprise a bearing surface 600 projecting, with respect to the lower surface 72 of the bundle of optical fibers 70, towards the second display element 2 nearest of the first display element 1 to protect the bundle of optical fibers 70.

  • the device 100 comprises spacing means 60, at least part of which is constituted by upper elastic return means 61.
  • the device 100 comprises spacing means 60, at least one part of which comprises at least one rigid mechanical stop 62, as visible on the picture 2 .

  • the picture 3 illustrates an adjustment of the distance by adjusting the position of the board of the second display element 2 on its shaft 29, and by taking up the play in the pivots 92 with an upper magnet 63. Taking up the play by an elastic element is also possible.
  • At least one second display element 2 is pivotable about a pivot axis D and comprises a shaft 29 guided in at least one bearing 92 that comprises the fixed part 50 and/or the first display element 1, and comprises a magnetized or ferromagnetic zone 28 eccentric with respect to this shaft 29, and the magnetic return means upper 63 are arranged to cooperate in attraction or repulsion with this magnetized or ferromagnetic zone 28.

  • This type of window 80 and dial 1 is particularly judicious with the use of a flexible needle.
  • the hand deforms and touches the dial or the crystal. It is therefore judicious to combine the flexible hand (for example for the minutes) with a sapphire aperture (which displays the time) according to the invention to prevent the flexible minute hand from interfering with another hand (for example the hour hand if this display had not been made in the window).
  • the invention also relates to a timepiece 1000, in particular a watch, comprising at least one such display device 100.
